GitHub user chamikaramj opened a pull request:
https://github.com/apache/incubator-beam/pull/1385
Fixes couple of issues of FileBasedSource.
(1) Updates code so that a user-specified coder properly gets set to splits.
(2) Currently each SingleFileSource takes a reference to FileBasedSource while FileBasedSource
takes a reference to Concatsource. ConcatSource has a reference to list of SingleFileSources.
This results in quadratic space complexity when serializing splits of a FileBasedSource. This
CL fixes this by making sure that FileBasedSource is cloned before taking a reference to
ConcatSource

Fixes a couple of issues of FileBasedSource.
(1) Updates code so that a user-specified coder properly gets set to sub-sources.
(2) Currently each SingleFileSource takes a reference to FileBasedSource while FileBasedSource
takes a reference to Concatsource. ConcatSource has a reference to list of SingleFileSources.
This results in quadratic space complexity when serializing splits of a FileBasedSource. This
